How do you get rid of pneumonitis?
Treatments for pneumonitis
- Corticosteroids: Prednisone (Rayos) and other steroid drugs bring down inflammation in your lungs.
- Oxygen therapy: If you’re very short of breath, you can breathe in oxygen through a mask or prongs in your nose.
- Bronchodilators: These medicines relax the airways to help you breathe easier.

Can methotrexate cause lung injury in patients with primary CNS lymphoma?
Acute lung injury in a patient receiving a high dose regimen for haematological malignancies has not been reported previously. We present one such case of methotrexate related acute lung injury in a patient of primary CNS lymphoma receiving high dose methotrexate. Introduction
